We're constantly pushing these materials and processes to the extreme to see what will happen. It's an insight into things that you don't normally see.

Fun for us just happens to be screwing around with anything that gets our attention and is thought-provoking.

We've found that the biggest thing as far as the danger is simply pressure.When we work with explosives, we've got bomb technicians there, bomb-squad guys who go into unknown situations all the time, and they've dealt with it safely.

From our point of view, we're just curious, we're poking around and having fun. If it's science, if it's accurate, if it's not accurate, we did the best we can to keep things clean and understandable, but we're just having fun, so sue us if we got something wrong.

Science isn't just for scientists and guys in lab coats. It's something that everybody can do.

I think LEGOs are one of the best toys ever developed. While LEGOs are sold in kits in order to build specific things, there [are] very few people who leave their LEGOs in those kits. It very rapidly becomes an open system where you can build whatever you want. That's the one thing that signifies my entire life and my career. I learned at an early age that I could make the things that I wanted. That's a very powerful thing to realize as a kid. LEGOs were a key part of that.

I would love to have access to a company like Caterpillar. I would make all their stuff remote controlled and work ten times as fast.
